Music ensembles typically have a leader; in jazz bands, rock and pop groups and similar ensembles, this is the band leader. In classical music, orchestras, concert bands and choirs are led by a conductor; in orchestra, the concertmaster (principal first violin player) is the instrumentalist leader of the orchestra. In orchestras, the individual sections also have leaders, typically called the "principal" of the section (e.g., the leader of the viola section is called the "principal viola"). Conductors are also used in jazzbig bands and in some very large rock or pop ensembles (e.g., a rock concert that includes a string section, a horn section and a choir which are accompanying a rock band's performance).

The string quintet is a common type of group, it is similar to the string quartet, but with an additional viola, cello, or more rarely, the addition of a double bass. Terms such as "piano quintet" or "clarinet quintet" frequently refer to a string quartet plus a fifth instrument. Mozart's Clarinet Quintet is similarly a piece written for an ensemble consisting of two violins, a viola, a cello and a clarinet, the last being the exceptional addition to a "normal" string quartet.

Some other quintets in classical music are the wind quintet, usually consisting of flute, oboe, clarinet, bassoon and horn; the brass quintet, consisting of two trumpets, one horn, a trombone and a tuba; and the reed quintet, consisting of an oboe, a soprano clarinet, a saxophone, a bass clarinet, and a bassoon.

Classical chamber ensembles of six (sextet), seven (septet), or eight musicians (octet) are fairly common; use of latinate terms for larger groups is rare, except for the nonet (nine musicians). In most cases, a larger classical group is referred to as an orchestra of some type or a concert band. A small orchestra with fifteen to thirty members (violins, violas, four cellos, two or three double basses, and several woodwind or brass instruments) is called a chamber orchestra. A sinfonietta usually denotes a somewhat smaller orchestra (though still not a chamber orchestra). Larger orchestras are called symphony orchestras (see below) or philharmonic orchestras.[1]

A symphony orchestra is an ensemble usually comprising at least thirty musicians; the number of players is typically between fifty and ninety-five and may exceed one hundred. A symphony orchestra is divided into families of instruments; in the string family, there are sections of violins (I and II), violas, cellos (often eight), and basses (often from six to eight). The standard woodwind section consists of flutes (one doubling piccolo), oboes (one doubling English horn), soprano clarinets (one doubling bass clarinet), and bassoons (one doubling contrabassoon), the standard brass section consists of horns, trumpets, trombones, and tuba. The percussion section includes the timpani, bass drum, snare drum, and any other percussion instruments called for in a score (e.g., triangle, glockenspiel, chimes, cymbals, wood blocks, etc.). In Baroque music (1600–1750) and music from the early Classical period music (1750–1820), the percussion parts in orchestral works may only include timpani.[clarification needed]

A concert band is a large classical ensemble generally made up of between 40 and 70 musicians from the woodwind, brass, and percussion families, along with the double bass, the concert band has a larger number and variety of wind instruments than the symphony orchestra, but does not have a string section (although a single double bass is common in concert bands). The woodwind section of a concert band consists of piccolo, flutes, oboes (one doubling English horn), bassoons (one doubling contrabassoon), soprano clarinets (one doubling E♭ clarinet, one doubling alto clarinet), bass clarinets (one doubling contrabass clarinet or contra-alto clarinet), alto saxophones (one doubling soprano saxophone), tenor saxophone, and baritone saxophone. The brass section consists of horns, trumpets or cornets, trombones, euphoniums, and tubas, the percussion section consists of the timpani, bass drum, snare drum, and any other percussion instruments called for in a score (e.g., triangle, glockenspiel, chimes, cymbals, wood blocks, etc.).

When orchestras perform baroque music (from the 17th century and early 18th century), they may also use a harpsichord or pipe organ, playing the continuo part. When orchestras perform Romantic-era music (from the 19th century), they may also use harps or unusual instruments such as the wind machine or cannons. When orchestras perform music from the 20th century or the 21st century, occasionally instruments such as electric guitar, theremin, or even an electronic synthesizer may be used.

In jazz, there are several types of trios. One type of jazz trio is formed with a piano player, a bass player and a drummer. Another type of jazz trio that became popular in the 1950s and 1960s is the organ trio, which is composed of a Hammond organ player, a drummer, and a third instrumentalist (either a saxophone player or an electric jazz guitarist). In organ trios, the Hammond organ player performs the bass line on the organ bass pedals while simultaneously playing chords or lead lines on the keyboard manuals. Other types of trios include the "drummer-less" trio, which consists of a piano player, a double bassist, and a horn (saxophone or trumpet) or guitar player; and the jazz trio with a horn player (saxophone or trumpet), double bass player, and a drummer. In the latter type of trio, the lack of a chordal instrument means that the horn player and the bassist have to imply the changing harmonies with their improvised lines.

Jazz quartets typically add a horn (the generic jazz name for saxophones, trombones, trumpets, or any other wind or brass instrument commonly associated with jazz) to one of the jazz trios described above. Slightly larger jazz ensembles, such as quintets (five instruments) or sextets (six instruments) typically add other soloing instruments to the basic quartet formation, such as different types of saxophones (e.g., alto saxophone, tenor saxophone, etc.) or an additional chordal instrument.

The lineup of larger jazz ensembles can vary considerably, depending on the style of jazz being performed; in a 1920s-style dixieland jazz band, a larger ensemble would be formed by adding a banjo player, woodwind instruments, as with the clarinet, or additional horns (saxophones, trumpets, trombones) to one of the smaller groups. In a 1930s-style Swing big band, a larger ensemble is formed by adding "sections" of like instruments, such as a saxophone section, a trumpet section and a trombone section, which perform arranged "horn lines" to accompany the ensemble, some Swing bands also added a string section for a lush sound. In a 1970s-style jazz fusion ensemble, a larger ensemble is often formed by adding additional percussionists or sometimes a saxophone player, who would "double" or "triple" (meaning that they would also be proficient at the clarinet, flute or both). Larger jazz ensembles are also formed by the addition of other soloing instruments.

Two-member rock and pop bands are relatively rare, because of the difficulty in providing all of the musical elements which are part of the rock or pop sound (vocals, chords, bass lines, and percussion or drumming). Two-member rock and pop bands typically omit one of these musical elements; in many cases, two-member bands will omit a drummer, since guitars, bass guitars, and keyboards can all be used to provide a rhythmic pulse.

When electronic sequencers became widely available in the 1980s, this made it easier for two-member bands to add in musical elements that the two band members were not able to perform. Sequencers allowed bands to pre-program some elements of their performance, such as an electronic drum part and a synth-bass line. Two-member pop music bands such as Soft Cell, Blancmange and Yazoo used pre-programmed sequencers. Other pop bands from the 1980s which were ostensibly fronted by two performers, such as Wham!, Eurythmics and Tears for Fears, were not actually two-piece ensembles, because other instrumental musicians were used "behind the scenes"[clarification needed] to fill out the sound.

W.A.S.P. guitarist Doug Blair is also known for his work in the two-piece progressive rock band signal2noise, where he acts as the lead guitarist and bassist at the same time, thanks to a special custom instrument he invented (an electric guitar with five regular guitar strings paired with three bass guitar strings). Heisenflei of Los Angeles duo The Pity Party plays drums, keyboards, and sings simultaneously. Providence-based Lightning Bolt is a two-member band. Bassist Brian Gibson augments his playing with delay pedals, pitch shifters, looping devices and other pedals, occasionally creating harmony. Local H, Blood Red Shoes, PS I Love You, The Redmond Barry's and Warship are other prominent two-person experimental rock bands.

Founded in 2013 Royal Blood is an unusual example of a two-piece band that utilise bass and drums, relying on extensive use of effects to produce a "full" sound.[citation needed]

An alternative to the power trio are organ trios formed with an electric guitarist, a drummer and a keyboardist, although organ trios are most commonly associated with 1950s and 1960s jazz organ trio groups such as those led by organist Jimmy Smith, there are also organ trios in rock-oriented styles, such as jazz-rock fusion and Grateful Dead-influenced jam bands such as Medeski Martin & Wood. In organ trios, the keyboard player typically plays a Hammond organ or similar instrument, which permits the keyboard player to perform bass lines, chords, and lead lines, one example being hard rock band Zebra. A variant of the organ trio are trios formed with an electric bassist, a drummer and an electronic keyboardist (playing synthesizers) such as the progressive rock band Emerson, Lake & Palmer, Triumvirat, and Atomic Rooster. Another variation is to have a vocalist, a guitarist and a drummer, an example being Yeah Yeah Yeahs. Another variation is two guitars, a bassist, and a drum machine, examples including Magic Wands and Big Black.

A power trio with the guitarist on lead vocals is a popular record company lineup, as the guitarist and singer will usually be the songwriter. Therefore, the label only has to present one "face"[clarification needed] to the public. The backing band may or may not be featured in publicity. If the backup band is not marketed as an integral part of the group, this gives the record company more flexibility to replace band members or use substitute musicians, this lineup often leads to songs that are fairly simple and accessible, as the frontman (or frontwoman) will have to sing and play guitar at the same time.

Other times, the vocalist will bring another musical "voice" to the table, most commonly a harmonica or percussion; Mick Jagger, for example, played harmonica and percussion instruments like maracas and tambourine whilst singing at the same time. Keith Relf of the Yardbirds played harmonica frequently, though not often while also singing. Ozzy Osbourne was also known to play the harmonica on some occasions (i.e. "The Wizard" by Black Sabbath). Vocalist Robert Brown of lesser known steampunk band Abney Park plays harmonica, accordion, and darbuka in addition to mandolin. Flutes are also commonly used by vocalists, most notably Ian Anderson of Jethro Tull and Ray Thomas of the Moody Blues, though these are difficult to play while singing at the same time.

A less common lineup is to have lead vocals, two guitarists of varying types and two drummers, e.g. Adam and the Ants.

Although they are quite uncommon, larger bands have long been a part of rock and pop music, in part due to the influence of the "singer accompanied with orchestra" model inherited from popular big-band jazz and swing and popularized by Frank Sinatra and Ella Fitzgerald.To create larger ensembles, rock bands often add an additional guitarist, an additional keyboardist, additional percussionists or second drummer, an entire horn section, and even a flautist. An example of a six-member rock band is Toto with a lead vocalist, guitarist, bassist, two keyboard players, and drummer, the American heavy metal band Slipknot is composed of nine members, with a vocalist, two guitarists, a drummer, a bassist, two custom percussionists/backing vocalists, a turntablist, and a sampler/keyboardist.

In larger groups (such as The Band), instrumentalists could play multiple instruments, which enabled the ensemble to create a wider variety of instrument combinations. More modern examples of such a band are Arcade Fire and Edward Sharpe and the Magnetic Zeros. More rarely, rock or pop groups will be accompanied in concerts by a full or partial symphony orchestra, where lush string-orchestra arrangements are used to flesh out the sound of slow ballads.

Women have a high prominence in many popular music styles as singers. However, professional women instrumentalists are uncommon in popular music, especially in rock genres such as heavy metal. "[P]laying in a band is largely a male homosocial activity, that is, learning to play in a band is largely a peer-based... experience, shaped by existing sex-segregated friendship networks.[3] As well, rock music "...is often defined as a form of male rebellion vis-à-vis female bedroom culture."[4] In popular music, there has been a gendered "distinction between public (male) and private (female) participation" in music.[4] "[S]everal scholars have argued that men exclude women from bands or from the bands' rehearsals, recordings, performances, and other social activities."[5] "Women are mainly regarded as passive and private consumers of allegedly slick, prefabricated – hence, inferior – pop music..., excluding them from participating as high status rock musicians."[5] One of the reasons that there are rarely mixed gender bands is that "bands operate as tight-knit units in which homosocial solidarity – social bonds between people of the same sex... – plays a crucial role."[5] In the 1960s pop music scene, "[s]inging was sometimes an acceptable pastime for a girl, but playing an instrument...simply wasn't done."[6]

"The rebellion of rock music was largely a male rebellion; the women—often, in the 1950s and '60s, girls in their teens—in rock usually sang songs as personæ utterly dependent on their macho boyfriends...". Philip Auslander says that "Although there were many women in rock by the late 1960s, most performed only as singers, a traditionally feminine position in popular music". Though some women played instruments in American all-female garage rock bands, none of these bands achieved more than regional success. So they "did not provide viable templates for women's on-going participation in rock";[7]:2–3 in relation to the gender composition of heavy metal bands, it has been said that "[h]eavy metal performers are almost exclusively male"[8] "...[a]t least until the mid-1980s"[9] apart from "...exceptions such as Girlschool."[8] However, "...now [in the 2010s] maybe more than ever–strong metal women have put up their dukes and got down to it",[10] "carv[ing] out a considerable place for [them]selves."[11] When Suzi Quatro emerged in 1973, "no other prominent female musician worked in rock simultaneously as a singer, instrumentalist, songwriter, and bandleader".[7]:2 According to Auslander, she was "kicking down the male door in rock and roll and proving that a female musician ... and this is a point I am extremely concerned about ... could play as well if not better than the boys".[7]:3

This section needs expansion. You can help by adding to it.(March 2012)

Sung dramas such as operas and musicals usually have numbers where several of the principals are singing together, either on their own or with the chorus, such numbers (duets, trios, etc.) are also referred to as 'ensembles'.

A choir is a group of voices. By analogy, sometimes a group of similar instruments in a symphony orchestra are referred to as a choir, for example, the woodwind instruments of a symphony orchestra could be called the woodwind choir.

A group that plays popular music or military music is usually called a band; a drum and bugle corps is a type of the latter. These bands perform a wide range of music, ranging from arrangements of jazz orchestral, or popular music to military-style marches. Drum corps perform on brass and percussion instruments only. Drum and Bugle Corps incorporate costumes, hats, and pageantry in their performances.

Mexican Mariachi groups typically consist of at least two violins, two trumpets, one Spanish guitar, one vihuela (a high-pitched, five-string guitar), and one Guitarrón (a Mexican acoustic bass that is roughly guitar-shaped), and one or more singers.

Classical music
–
Classical music is art music produced or rooted in the traditions of Western music, including both liturgical and secular music. The central norms of this tradition became codified between 1550 and 1900, which is known as the common-practice period, Western staff notation is used by composers to indicate to the performer the pitches, tempo, meter and rhythms for a piece of music. This can leave less room for such as improvisation and ad libitum ornamentation. The term classical music did not appear until the early 19th century, the earliest reference to classical music recorded by the Oxford English Dictionary is from about 1836. This score typically determines details of rhythm, pitch, and, the written quality of the music has enabled a high level of complexity within them, J. S. The use of written notation also preserves a record of the works, Musical notation enables 2000s-era performers to sing a choral work from the 1300s Renaissance era or a 1700s Baroque concerto with many of the features of the music being reproduced. That said, the score does not provide complete and exact instructions on how to perform a historical work, even if the tempo is written with an Italian instruction, we do not know exactly how fast the piece should be played. Bach was particularly noted for his complex improvisations, during the Classical era, the composer-performer Mozart was noted for his ability to improvise melodies in different styles. During the Classical era, some virtuoso soloists would improvise the cadenza sections of a concerto, during the Romantic era, Beethoven would improvise at the piano. The instruments currently used in most classical music were largely invented before the mid-19th century and they consist of the instruments found in an orchestra or in a concert band, together with several other solo instruments. The symphony orchestra is the most widely known medium for music and includes members of the string, woodwind, brass. The concert band consists of members of the woodwind, brass and it generally has a larger variety and number of woodwind and brass instruments than the orchestra but does not have a string section. However, many bands use a double bass. Many of the used to perform medieval music still exist. Medieval instruments included the flute, the recorder and plucked string instruments like the lute. As well, early versions of the organ, fiddle, Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut, during the earlier medieval period, the vocal music from the liturgical genre, predominantly Gregorian chant, was monophonic, using a single, unaccompanied vocal melody line. Polyphonic vocal genres, which used multiple independent vocal melodies, began to develop during the medieval era, becoming prevalent by the later 13th

Instrumental music
–
An instrumental is a musical composition or recording without lyrics, or singing, although it might include some inarticulate vocals, such as shouted backup vocals in a Big Band setting. The music is primarily or exclusively produced by musical instruments, if the instrumental section highlights the skill, musicality, and often the virtuosity of a particular performer, the section may be called a solo. If the instruments are percussion instruments, the interlude can be called a percussion interlude or percussion break and these interludes are a form of break in the song. One example of a genre in which both vocal/instrumental and solely instrumental songs are produced is blues, another example of a genre in popular culture is Hip Hop, Pop, and R&B. Many upcoming or rising artists in Hip Hop, Pop, and R&B will find an instrumental online on a website, like www. beatsbytoon. com, an instrumental version of a song which otherwise features vocals is also known as a -1. The opposite of instrumental music, that is, music for voices alone, without any accompaniment instruments, is a cappella, an Italian phrase that means in the chapel. In early music, instruments such as trumpet and drums were considered outdoor instruments, a capella music exists in both Classical music choir pieces and in popular music styles such as doo wop groups and Barbershop quartets. Some recordings which include brief examples of the voice are typically considered instrumentals. An ominous statement at the end Inclusion of field recordings which may or may not contain non-lyrical words, a few songs categorized as instrumentals may even include actual vocals, if they appear only as a short part of an extended piece. Falling just outside that definition is Theme From Shaft by Isaac Hayes. com with a sample of each

Quartet
–
In music, a quartet or quartette is an ensemble of four singers or instrumental performers, or a musical composition for four voices or instruments. In Classical music, the most important combination of four instruments in music is the string quartet. String quartets most often consist of two violins, a viola, and a cello, the particular choice and number of instruments derives from the registers of the human voice, soprano, alto, tenor and bass. In the string quartet, two play the soprano and alto vocal registers, the viola plays the tenor register. The Italian composer Luigi Boccherini, wrote more than 100 string quartets, less often, string quartets are written for other combinations of the standard string ensemble. These include quartets for one violin, two violas, and one cello, notably by Carl Stamitz and others, and for one violin, one viola, another common standard classical quartet is the piano quartet, consisting of violin, viola, cello, and piano. Romantic composers Beethoven, Brahms, and Mendelssohn each wrote three important compositions in this form, and Mozart, Dvořák, and Gabriel Fauré each wrote two. Wind quartets are scored either the same as a quartet with the wind instrument replacing the first violin or are groups of four wind instruments. Among the latter, the SATB format woodwind quartet of flute, oboe, clarinet, an example of a wind quartet featuring four of the same types of wind instruments is the saxophone quartet, consisting of soprano saxophone, alto saxophone, tenor saxophone and baritone saxophone or. Often a second alto may be substituted for the part or a bass saxophone may be substituted for the baritone. Compositions for four singers have been written for quartets a cappella, accompanied by instruments, such as a piano, Brahms and Schubert wrote numerous pieces for four voices that were once popular in private salons, although they are seldom performed today. Vocal quartets also feature within larger classical compositions, such as opera, choral works, the final movement of Beethovens Ninth Symphony and the Verdi Requiem are two examples of renowned concert works that include vocal quartets. The baroque quartet is a form of composition similar to the trio sonata. The solo instruments could be strings or wind instruments, examples of baroque quartets are Telemanns Paris quartets. Quartets are popular in jazz and jazz fusion music, jazz quartet ensembles are often composed of a horn, a chordal instrument, a bass instrument and a drum kit. This configuration is sometimes modified by using a second horn replacing the instrument, such as a trumpet and saxophone with string bass and drum kit. In 20th century Western popular music, the vocal quartet usually refers to ensembles of four singers of the same gender. This is particularly common for barbershop quartets and Gospel quartets, some well-known female US vocal quartets include The Carter Sisters, The Forester Sisters, The Chiffons, The Chordettes, The Lennon Sisters, and En Vogue

Orchestra
–
The term orchestra derives from the Greek ὀρχήστρα, the name for the area in front of a stage in ancient Greek theatre reserved for the Greek chorus. A full-size orchestra may sometimes be called an orchestra or philharmonic orchestra. The actual number of employed in a given performance may vary from seventy to over one hundred musicians, depending on the work being played. The term chamber orchestra usually refers to smaller-sized ensembles of about fifty musicians or fewer, the typical orchestra grew in size throughout the 18th and 19th centuries, reaching a peak with the large orchestras called for in the works of Richard Wagner, and later, Gustav Mahler. Orchestras are usually led by a conductor who directs the performance with movements of the hands and arms, the conductor unifies the orchestra, sets the tempo and shapes the sound of the ensemble. The first violin, commonly called the concertmaster, also plays an important role in leading the musicians, the typical symphony orchestra consists of four groups of related musical instruments called the woodwinds, brass, percussion, and strings. The orchestra, depending on the size, contains almost all of the instruments in each group. Chamber orchestra usually refers to smaller-sized ensembles, a chamber orchestra might employ as many as fifty musicians. The term concert orchestra may also be used, as in the BBC Concert Orchestra, the so-called standard complement of doubled winds and brass in the orchestra from the first half of the 19th century is generally attributed to the forces called for by Beethoven. The composers instrumentation almost always included paired flutes, oboes, clarinets, bassoons, horns, the exceptions to this are his Symphony No. 4, Violin Concerto, and Piano Concerto No,4, which each specify a single flute. Beethoven carefully calculated the expansion of this particular timbral palette in Symphonies 3,5,6, the third horn in the Eroica Symphony arrives to provide not only some harmonic flexibility, but also the effect of choral brass in the Trio movement. Piccolo, contrabassoon, and trombones add to the finale of his Symphony No.5. A piccolo and a pair of trombones help deliver the effect of storm and sunshine in the Sixth, for several decades after his death, symphonic instrumentation was faithful to Beethovens well-established model, with few exceptions. Apart from the core orchestral complement, various instruments are called for occasionally. These include the guitar, heckelphone, flugelhorn, cornet, harpsichord. Saxophones, for example, appear in some 19th- through 21st-century scores.6 and 9 and William Waltons Belshazzars Feast, and many other works as a member of the orchestral ensemble. The euphonium is featured in a few late Romantic and 20th-century works, usually playing parts marked tenor tuba, including Gustav Holsts The Planets, cornets appear in Pyotr Ilyich Tchaikovskys ballet Swan Lake, Claude Debussys La Mer, and several orchestral works by Hector Berlioz

5.
Choir
–
A choir is a musical ensemble of singers. Choral music, in turn, is the music specifically for such an ensemble to perform. Choirs may perform music from the classical repertoire, which spans from the Medieval era to the present. Most choirs are led by a conductor, who leads the performances with arm, a body of singers who perform together as a group is called a choir or chorus. The former term is often applied to groups affiliated with a church and the second to groups that perform in theatres or concert halls. Choirs may sing without instrumental accompaniment, with the accompaniment of a piano or pipe organ, with a small ensemble, choirs are often led by a conductor or choirmaster. Other than four, the most common number of parts are three, five, six, and eight, choirs can sing with or without instrumental accompaniment. Singing without accompaniment is called a cappella singing, many choirs perform in one or many locations such as a church, opera house, or school hall. In some cases choirs join up to become one mass choir that performs for a special concert, in this case they provide a series of songs or musical works to celebrate and provide entertainment to others. Conducting is the art of directing a musical performance, such as a concert, by way of visible gestures with the hands, arms, face. The primary duties of the conductor or choirmaster are to unify performers, set the tempo, execute clear preparations and beats, and to listen critically and shape the sound of the ensemble. The conductor or choral director typically stands on a raised platform, many choral conductors use their hands to conduct. In the 2010s, most conductors do not play an instrument when conducting, although in earlier periods of music history. In Baroque music from the 1600s to the 1750s, conductors performing in the 2010s may lead an ensemble while playing a harpsichord or the violin, conducting while playing a piano may also be done with musical theatre pit orchestras. Communication is typically non-verbal during a performance, however, in rehearsals, frequent interruptions allow the conductor to give verbal directions as to how the music should be sung. Conductors act as guides to the choirs they conduct and they choose the works to be performed and study their scores, to which they may make certain adjustments, work out their interpretation, and relay their vision to the singers. Choral conductors may also have to conduct instrumental ensembles such as if the choir is singing a piece for choir. They may also attend to matters, such as scheduling rehearsals, planning a concert season, hearing auditions

Doo-wop
–
Built upon vocal harmony, doo-wop was one of the most mainstream, pop-oriented R&B styles of the time. Doo-wop features vocal harmony, nonsense syllables, a simple beat, sometimes little or no instrumentation. The first record to use the syllables doo-wop was the 1955 hit When You Dance by The Turbans, the term doo-wop first appeared in print in 1961. During the late 1950s many Italian-American groups contributed a significant part in the doo-wop scene, the peak of doo-wop was in 1961. Doo-wops influence continued in soul, pop, and rock groups of the 1960s, at various times in the 1970s, 1980s, and 1990s, the genre has seen revivals. Doo-wop was a precursor to many of the African-American musical styles seen today, an evolution of jazz and blues, doo-wop also influenced many of the major rock and roll groups that defined the later decades of the 20th century. Doo-wop is iconic for its beats and using the off-beat to keep time. Doo-wop laid the foundation for musical innovations, for example. These were generally slow songs in swing time with simple instrumentation, the subject of the lyrics was generally love and relationships. This characteristic harmonic layout was combined with the AABA chorus form typical for Tin Pan Alley pop, a second stream of doo-wop oriented itself to the harmonic, formal and melodic means of jump blues. From the outset, singers gathered on street corners, and in subways, for instance, Count Every Star by The Ravens, includes vocalizations imitating the doomph, doomph plucking of a double bass. This art dates to The Mills Brothers, who first came to fame in the 1930s with their mimicking of instrumental music, radio, gramophone, and cinema inspired imitation in many U. S. cities. The late 1940s and early 1950s brought the bird groups, The Swallows. A number of names are also drawn from cars. The Orioles helped develop the sound with their hits Its Too Soon to Know. The term doo-wop first appeared in print in 1961 in the Chicago Defender, the phrase was attributed to radio disc jockey Gus Gossert but Gossert suggested doo-wop was already in use to categorize the music in California. The first record to use the syllables doo-wop in the refrain was the 1955 hit When You Dance by The Turbans, previously, the scat backing vocal doo-wop is heard in The Clovers 1953 release Good Lovin and in the chorus of Carlyle Dundee & The Dundees 1954 song Never. After some time, the term doo-wop finally caught on as both a description and category for R&B vocal group harmony, the definition expanded backward to include rhythm and blues groups from the mid-1950s, then cascaded even further back to include groups from the 1940s

Popular music
–
Popular music is music with wide appeal that is typically distributed to large audiences through the music industry. These forms and styles can be enjoyed and performed by people with little or no musical training and it stands in contrast to both art music and traditional or folk music. Art music was historically disseminated through the performances of music, although since the beginning of the recording industry. Traditional music forms such as blues songs or hymns were passed along orally, or to smaller. The original application of the term is to music of the 1880s Tin Pan Alley period in the United States, although popular music sometimes is known as pop music, the two terms are not interchangeable. Popular music songs and pieces typically have easily singable melodies, in the 2000s, with songs and pieces available as digital sound files, it has become easier for music to spread from one country or region to another. Some popular music forms have become global, while others have an appeal within the culture of their origin. Through the mixture of genres, new popular music forms are created to reflect the ideals of a global culture. The examples of Africa, Indonesia and the Middle East show how Western pop music styles can blend with local traditions to create new hybrid styles. Sales of recordings or sheet music are one measure, middleton and Manuel note that this definition has problems because multiple listens or plays of the same song or piece are not counted. Manuel states that one criticism of music is that it is produced by large media conglomerates and passively consumed by the public. He claims that the listeners in the scenario would not have been able to make the choice of their favorite music, moreover, understandings of popular music have changed with time. A societys popular music reflects the ideals that are prevalent at the time it is performed or published, david Riesman states that the youth audiences of popular music fit into either a majority group or a subculture. The majority group listens to the commercially produced styles while the subcultures find a minority style to transmit their own values and this allows youth to choose what music they identify with, which gives them power as consumers to control the market of popular music. Form in popular music is most often sectional, the most common sections being verse, chorus or refrain, other common forms include thirty-two-bar form, chorus form *, and twelve-bar blues. Popular music songs are rarely composed using different music for each stanza of the lyrics, the verse and chorus are considered the primary elements. Each verse usually has the melody, but the lyrics change for most verses. The chorus usually has a phrase and a key lyrical line which is repeated

Band (rock and pop)
–
A rock band or pop band is a small musical ensemble which performs rock music, pop music or a related genre. The four-piece band is the most common configuration in rock and pop music, before the development of the electronic keyboard, the configuration was typically two guitarists, a bassist, and a drummer. Another common formation is a vocalist who does not play an instrument, electric guitarist, bass guitarist, instrumentally, these bands can be considered as trios. The smallest ensemble that is used in rock music is the trio format. Two-member rock and pop bands are relatively rare, because of the difficulty in providing all of the elements which are part of the rock or pop sound. Some well-known power trios with the guitarist on lead vocals are The Jimi Hendrix Experience, Stevie Ray Vaughan and Double Trouble, Nirvana, The Jam, and ZZ Top. Two-member rock and pop bands are relatively rare, because of the difficulty in providing all of the elements which are part of the rock or pop sound. Two-member rock and pop bands typically omit one of musical elements. In many cases, two-member bands will omit a drummer, since guitars, bass guitars, honeyblood, Diet Cig and Royal Blood. When electronic sequencers became widely available in the 1980s, this made it easier for bands to add in musical elements that the two band members were not able to perform. Sequencers allowed bands to pre-program some elements of their performance, such as a drum part. Two-member pop music such as Soft Cell, Blancmange and Yazoo used pre-programmed sequencers. Other pop bands from the 1980s which were fronted by two performers, such as Wham. Eurythmics and Tears for Fears, were not actually two-piece ensembles, two-piece bands in rock music are quite rare. However, starting in the 2000s, blues-influenced rock bands such as The White Stripes and The Black Keys utilized a guitar, however, this is predated by the Flat Duo Jets and House of Freaks from the 1980s. Death from Above 1979 featured a drummer and bass guitarist, tenacious D is a two-guitar band, One Day as a Lion and The Dresden Dolls both feature a keyboardist and a drummer. The band Welk consists of a two-man psychedelic flute band, with the occasional synthesizer, two-person bands have grown in popularity in experimental rock music. Ratatat are a band that utilize a drum machine for beats

Figured bass
–
Basso continuo parts, almost universal in the Baroque era, provided the harmonic structure of the music. The phrase is shortened to continuo, and the instrumentalists playing the continuo part are called the continuo group. The titles of many Baroque works make mention of the section, such as J. S. Bachs Concerto for Two Violins, Strings. The makeup of the group is often left to the discretion of the performers. At least one instrument capable of playing chords must be included, such as a harpsichord, organ, lute, theorbo, guitar, regal, or harp. In addition, any number of instruments play in the bass register may be included, such as cello, double bass, bass viol. The most common combination, at least in modern performances, is harpsichord and cello for instrumental works and secular works, such as operas. Harps, lutes, and other instruments are more typical of early 17th-century music. The keyboard player realizes a continuo part by playing, in addition to the bass line, notes above it to complete chords. The figured bass notation, described below, is a guide, but performers are expected to use their musical judgment. Experienced players sometimes incorporate motives found in the instrumental parts into their improvised chordal accompaniment. Modern editions of music usually supply a realized keyboard part, fully written out in staff notation for a player. With the rise in historically informed performance, however, the number of performers who are able to improvise their parts from the figures, as Baroque players would have done, has increased. Basso continuo, though a structural and identifying element of the Baroque period, continued to be used in many works, mostly sacred choral works. An example is C. P. E. Bachs Concerto in D minor for flute, strings and basso continuo. Examples of its use in the 19th century are rarer, but they do exist, masses by Anton Bruckner, Beethoven, the phrase tasto solo indicates that only the bass line is to be played for a short period, usually until the next figure is encountered. This instructs the chord-playing instrumentalist not to play any improvised chords for a period, composers were inconsistent in the usages described below. Especially in the 17th century, the numbers were omitted whenever the composer thought the chord was obvious, early composers such as Claudio Monteverdi often specified the octave by the use of compound intervals such as 10,11, and 15

Harpsichord
–
A harpsichord is a musical instrument played by means of a keyboard. It produces sound by plucking a string when a key is pressed, Harpsichord designates the whole family of similar plucked keyboard instruments, including the smaller virginals, muselar, and spinet. The harpsichord was used in Renaissance and Baroque music. During the late 18th century, it disappeared from the musical scene with the rise of the piano. In the 20th century, it made a resurgence, being used in historically informed performances of music, in compositions. Harpsichords vary in size and shape, but all have the basic functional arrangement. The player depresses a key that rocks over a pivot in the middle of its length, the other end of the key lifts a jack that holds a small plectrum, which plucks the string. When the player releases the key, the far end returns to its rest position, the plectrum, mounted on a tongue that can swivel backwards away from the string, passes the string without plucking it again. As the key reaches its rest position, a felt damper atop the jack stops the strings vibrations and these basic principles are explained in detail below. The keylever is a pivot, which rocks on a balance pin that passes through a hole drilled through the keylever. The jack is a thin, rectangular piece of wood that sits upright on the end of the keylever, the jacks are held in place by the registers. These are two strips of wood, which run in the gap between pinblock and bellyrail. The registers have rectangular mortises through which the pass as they can move up. The registers hold the jacks in the location needed to pluck the string. In the jack, a plectrum juts out almost horizontally and passes just under the string, historically, plectra were made of bird quill or leather, many modern harpsichords have plastic plectra. When the front of the key is pressed, the back of the key rises, the jack is lifted, the vertical motion of the jack is then stopped by the jackrail, which is covered with soft felt to muffle the impact. When the key is released, the falls back down under its own weight. This is made possible by having the plectrum held in a tongue attached with a pivot and a spring to the body of the jack

Cello
–
The cello or violoncello is a bowed or plucked string instrument with four strings tuned in perfect fifths. The strings from low to high are generally tuned to C2, G2, D3 and A3 and it is a member of the violin family of musical instruments, which also includes the violin and viola and the double bass. The cello is used as a musical instrument, as well as in chamber music ensembles, string orchestras, as a member of the string section of symphony orchestras. It is the second-largest and second lowest bowed string instrument in the symphony orchestra. Cello parts are written in the bass clef, but both tenor clef and treble clefs are used for higher-range parts, both in orchestral/chamber music parts and in solo cello works. A person who plays the cello is called a cellist or violoncellist, in a small Classical ensemble, such as a string quartet, the cello typically plays the bass part, the lowest-pitched musical line of the piece. In orchestra, in Baroque era and Classical music period, the cello plays the bass part. In Baroque era music, the cello is used to play the basso continuo bassline, in a Baroque performance, the cello player might be joined by other bass instruments, playing double bass, viol or other low-register instruments. The name cello is a contraction of the Italian violoncello, which means little violone, in modern symphony orchestras, it is the second largest stringed instrument. Thus, the name contained both the augmentative -one and the diminutive -cello. By the turn of the 20th century, it had become common to shorten the name to cello and it is now customary to use cello without apostrophe as the full designation. Viol is derived from the viola, which was derived from Medieval Latin vitula. Cellos are tuned in fifths, starting with C2, followed by G2, D3 and it is tuned in the same intervals as the viola, but an octave lower. Unlike the violin or viola but similar to the double bass, the cello is most closely associated with European classical music, and has been described as the closest sounding instrument to the human voice. The instrument is a part of the orchestra, as part of the string section. A large number of concertos and sonatas have been written for the cello, among the most well-known Baroque works for the cello are Johann Sebastian Bachs six unaccompanied Suites. The Prelude from the First Suite is particularly famous, romantic era repertoire includes the Robert Schumann Concerto, the Antonín Dvořák Concerto as well as the two sonatas and the Double Concerto by Johannes Brahms. The cello is increasingly common in traditional music, especially Scottish fiddle music

Musical instrument
–
A musical instrument is an instrument created or adapted to make musical sounds. In principle, any object that produces sound can be a musical instrument—it is through purpose that the object becomes a musical instrument, the history of musical instruments dates to the beginnings of human culture. Early musical instruments may have used for ritual, such as a trumpet to signal success on the hunt. Cultures eventually developed composition and performance of melodies for entertainment, Musical instruments evolved in step with changing applications. The date and origin of the first device considered an instrument is disputed. The oldest object that some refer to as a musical instrument. Some consensus dates early flutes to about 37,000 years ago, many early musical instruments were made from animal skins, bone, wood, and other non-durable materials. Musical instruments developed independently in many populated regions of the world, however, contact among civilizations caused rapid spread and adaptation of most instruments in places far from their origin. By the Middle Ages, instruments from Mesopotamia were in maritime Southeast Asia, development in the Americas occurred at a slower pace, but cultures of North, Central, and South America shared musical instruments. By 1400, musical instrument development slowed in areas and was dominated by the Occident. Musical instrument classification is a discipline in its own right, Instruments can be classified by their effective range, their material composition, their size, etc. However, the most common method, Hornbostel-Sachs, uses the means by which they produce sound. The academic study of instruments is called organology. Once humans moved from making sounds with their bodies—for example, by using objects to create music from sounds. Primitive instruments were designed to emulate natural sounds, and their purpose was ritual rather than entertainment. The concept of melody and the pursuit of musical composition were unknown to early players of musical instruments. A player sounding a flute to signal the start of a hunt does so without thought of the notion of making music. Musical instruments are constructed in an array of styles and shapes

Piano
–
The piano is an acoustic, stringed musical instrument invented around the year 1700, in which the strings are struck by hammers. It is played using a keyboard, which is a row of keys that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. The word piano is a form of pianoforte, the Italian term for the early 1700s versions of the instrument. The first fortepianos in the 1700s had a sound and smaller dynamic range. An acoustic piano usually has a wooden case surrounding the soundboard and metal strings. Pressing one or more keys on the keyboard causes a padded hammer to strike the strings. The hammer rebounds from the strings, and the continue to vibrate at their resonant frequency. These vibrations are transmitted through a bridge to a soundboard that amplifies by more efficiently coupling the acoustic energy to the air, when the key is released, a damper stops the strings vibration, ending the sound. Notes can be sustained, even when the keys are released by the fingers and thumbs and this means that the piano can play 88 different pitches, going from the deepest bass range to the highest treble. The black keys are for the accidentals, which are needed to play in all twelve keys, more rarely, some pianos have additional keys. Most notes have three strings, except for the bass that graduates from one to two, the strings are sounded when keys are pressed or struck, and silenced by dampers when the hands are lifted from the keyboard. There are two types of piano, the grand piano and the upright piano. The grand piano is used for Classical solos, chamber music and art song and it is used in jazz. The upright piano, which is compact, is the most popular type, as they are a better size for use in private homes for domestic music-making. During the nineteenth century, music publishers produced many works in arrangements for piano, so that music lovers could play. The piano is widely employed in classical, jazz, traditional and popular music for solo and ensemble performances, accompaniment, with technological advances, amplified electric pianos, electronic pianos, and digital pianos have also been developed. The electric piano became an instrument in the 1960s and 1970s genres of jazz fusion, funk music. The piano was founded on earlier technological innovations in keyboard instruments, pipe organs have been used since Antiquity, and as such, the development of pipe organs enabled instrument builders to learn about creating keyboard mechanisms for sounding pitches

String (music)
–
A string is the vibrating element that produces sound in string instruments such as the guitar, harp, piano, and members of the violin family. Strings are lengths of a material that a musical instrument holds under tension so that they can vibrate freely. Wound strings have a core of one material, with an overwinding of other materials and this is to make the string vibrate at the desired pitch, while maintaining a low profile and sufficient flexibility for playability. This enabled stringed instruments to be made with less thick bass strings, on string instruments that the player plucks or bows directly, this enabled instrument makers to use thinner strings for the lowest-pitched strings, which made the lower-pitch strings easier to play. The end of the string that mounts to the tuning mechanism is usually plain. Depending on the instrument, the other, fixed end may have either a plain, loop. When a ball or loop is used with a guitar, this ensures that the string stays fixed in the bridge of the guitar, when a ball or loop is used with a violin-family instrument, this keeps the string end fixed in the tailpiece. Fender Bullet strings have a cylinder for more stable tuning on guitars equipped with synchronized tremolo systems. Strings for some instruments may be wrapped with silk at the ends to protect the string, the color and pattern of the silk often identifies attributes of the string, such as manufacturer, size, intended pitch, etc. There are several varieties of wound strings available, the simplest wound strings are roundwound—with round wire wrapped in a tight spiral around either a round or hexagonal core. Such strings are usually simple to manufacture and the least expensive and they have several drawbacks, however, Roundwound strings have a bumpy surface profile that produce friction on the players fingertips. This causes squeaking sounds when the fingers slide over the strings. Roundwound strings higher friction surface profile may hasten fingerboard and fret wear, when the core is round, the winding is less secure and may rotate freely around the core, especially if the winding is damaged after use. Flatwound strings also have either a round or hex core, however, the winding wire has a rounded square cross-section that has a shallower profile when tightly wound. This makes for more playing, and decreased wear for frets. Squeaking sounds due to fingers sliding along the strings are also decreased significantly, flatwound strings also have a longer playable life because of smaller grooves for dirt and oil to build up in. On the other hand, flatwound strings sound less bright than roundwounds, flatwounds also usually cost more than roundwounds because of less demand, less production, and higher overhead costs. Manufacturing is also difficult, as precise alignment of the flat sides of the winding must be maintained

Wind instrument
–
The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of wind instruments, sound is produced by blowing through a reed. Using different air columns for different tones, such as in the pan flute and this method is used on nearly all brass instruments. Changing the length of the air column by lengthening and/or shortening the tube using a sliding mechanism. This method is used on the trombone and the slide whistle, changing the frequency of vibration through opening or closing holes in the side of the tube. This can be done by covering the holes with fingers or pressing a key which then closes the hole and this method is used in nearly all woodwind instruments. Making the column of air vibrate at different harmonics without changing the length of the column of air, almost all wind instruments use the last method, often in combination with one of the others, to extend their register. A more accurate way to determine whether an instrument is brass or woodwind is to examine how the player produces sound, in brass instruments, the players lips vibrate, causing the air within the instrument to vibrate. For example, the saxophone is typically made of brass, but is classified as an instrument because it produces sound with a vibrating reed. In the Hornbostel-Sachs scheme of musical instrument classification, wind instruments are classed as aerophones, sound production in all wind instruments depends on the entry of air into a flow-control valve attached to a resonant chamber. The resonator is typically a long cylindrical or conical tube, open at the far end, a pulse of high pressure from the valve will travel down the tube at the speed of sound. It will be reflected from the end as a return pulse of low pressure. Under suitable conditions, the valve will reflect the pulse back, with increased energy, Reed instruments such as the clarinet or oboe have a flexible reed or reeds at the mouthpiece, forming a pressure-controlled valve. Standing waves inside the tube will be odd multiples of a quarter-wavelength, with a pressure anti-node at the mouthpiece, the reed vibrates at a rate determined by the resonator. For Lip Reed instruments, the controls the tension in their lips so that they vibrate under the influence of the air flow through them. They adjust the vibration so that the lips are most closed, and the air flow is lowest, standing waves inside the tube will be odd multiples of a quarter-wavelength, with a pressure anti-node at the mouthpiece, and a pressure node at the open end. For Air Reed instruments, the thin grazing air sheet flowing across an opening in the pipe interacts with an edge to generate sound. The jet is generated by the player, when blowing through a thin slit, for recorders and flue organ pipes this slit is manufactured by the instrument maker and has a fixed geometry

String quartet
–
A string quartet is a musical ensemble of four string players – two violin players, a viola player and a cellist – or a piece written to be performed by such a group. The string quartet is one of the most prominent chamber ensembles in classical music, with most major composers, from the mid to late 18th century onwards, writing string quartets. The string quartet was developed into its current form by the Austrian composer Joseph Haydn, ever since Haydns day the string quartet has been considered a prestigious form and represents one of the true tests of the composers art. With four parts to play with, a composer working in anything like the key system has enough lines to fashion a full argument. The closely related characters of the four instruments, moreover, while they cover in combination an ample compass of pitch, do not lend themselves to indulgence in purely colouristic effects. Thus, in ways the string quartet is pre-eminently the dialectical form of instrumental music. Quartet composition flourished in the Classical era, with Wolfgang Amadeus Mozart, Ludwig van Beethoven, in the 21st century it remains an important and refined musical form. Some quartets play together for years in ensembles which may be named after the first violinist. Well-known string quartets can be found in the list of string quartet ensembles, the early history of the string quartet is in many ways the history of Haydns journey with the genre. However, these composers showed no interest in exploring the development of the quartet as a medium. The origins of the quartet can be further traced back to the Baroque trio sonata. A very early example is a sonata for string ensemble by Gregorio Allegri that might be considered an important prototype string quartet. By the early 18th century, composers were often adding a third soloist, thus when Alessandro Scarlatti wrote a set of six works entitled Sonata à Quattro per due Violini, Violetta, e Violoncello senza Cembalo, this was a natural evolution from the existing tradition. The string quartet in its now accepted form came about with Haydn, even the composition of Haydns earliest string quartets owed more to chance than artistic imperative. Haydns early biographer Georg August Griesinger tells the story thus, The following purely chance circumstance had led him to try his luck at the composition of quartets. A Baron Fürnberg had a place in Weinzierl, several stages from Vienna, and he invited from time to time his pastor, his manager, Haydn, Fürnberg requested Haydn to compose something that could be performed by these four amateurs. Haydn went on to nine other quartets around this time. These works were published as his Op.1 and Op.2, one quartet went unpublished and they have five movements and take the form, fast movement, minuet and trio I, slow movement, minuet and trio II, and fast finale

Wind quintet
–
A wind quintet, also known as a woodwind quintet, is a group of five wind players. The term also applies to a composition for such a group, unlike the string quartet with its homogeneous blend of color, the instruments in a wind quintet differ from each other considerably in technique, idiom, and timbre. The modern wind quintet sprang from the ensemble favored in the court of Joseph II in late 18th century Vienna, two oboes, two clarinets, two horns, and two bassoons. It was Anton Reichas twenty-four quintets, begun in 1811, and the nine quintets of Franz Danzi that established the genre, and their pieces are still standards of the repertoire.

String section
–
The string section is the largest body of a single instrument category in the standard Classical orchestra. It normally consists of the first violins, the violins, the violas, the cellos. The first and second play the same types of instruments. The first violins are generally given the melody or higher-pitch musical lines, the second violins may play a harmony part, a countermelody or an accompaniment passage. In discussions of the instrumentation of a work, the phrase the strings or. An orchestra consisting solely of a section is called a string orchestra. Smaller string sections are used in jazz, pop and rock music arrangements, the most common seating arrangement in the 2000s is with first violins, second violins, violas and cello sections arrayed clockwise around the conductor, with basses behind the cellos on the right. The principal string players sit at the front of their section, closest to the conductor and on the row of performers which is closest to the audience. If space or numbers are limited, cellos and basses can be put in the middle, violins and violas on the left and winds to the right, this is the usual arrangement in orchestra pits. The seating may also be specified by the composer, as in Béla Bartóks Music for Strings, Percussion and Celesta, in some cases, due to space constraints or other issues, a different layout may be used. The inside player typically turns the pages of the part, while the player continues playing. In cases where a turn occurs during an essential musical part. There are more variations of set-up with the bass section, depending on the size of the section. There are not usually as many basses as cellos, so they are either in one row, or for a larger section, in some orchestras, some or all of the string sections may be placed on wooden risers, which are platforms that elevate the performers. The size of a section may be expressed with a formula of the type 10-10-8-10-6, designating the number of first violins, second violins, violas, cellos. The numbers can vary widely, Wagner in Die Walküre specifies 16-16-12-12-8, in general, music from the Baroque music era and the Classical music period used smaller string sections. During the contemporary era, some composers requested smaller string sections. In some regional orchestras, amateur orchestras and youth orchestras, the sections may be relatively small

Brass instrument
–
A brass instrument is a musical instrument that produces sound by sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the players lips. Brass instruments are also called labrosones, literally meaning lip-vibrated instruments, there are several factors involved in producing different pitches on a brass instrument. The view of most scholars is that the brass instrument should be defined by the way the sound is made, as above. Thus one finds brass instruments made of wood, like the alphorn, the cornett, the serpent, as valved instruments are predominant among the brasses today, a more thorough discussion of their workings can be found below. The valves are usually piston valves, but can be rotary valves, slide brass instruments use a slide to change the length of tubing. The main instruments in this category are the family, though valve trombones are occasionally used. The trombone familys ancestor, the sackbut, and the folk instrument bazooka are also in the slide family, there are two other families that have, in general, become functionally obsolete for practical purposes. Instruments of both types, however, are used for period-instrument performances of Baroque or Classical pieces. In more modern compositions, they are used for their intonation or tone color. Natural brass instruments only play notes in the harmonic series. These include the bugle and older variants of the trumpet and horn, the trumpet was a natural brass instrument prior to about 1795, and the horn before about 1820. In the 18th century, makers developed interchangeable crooks of different lengths, natural instruments are still played for period performances and some ceremonial functions, and are occasionally found in more modern scores, such as those by Richard Wagner and Richard Strauss. Keyed or Fingered brass instruments used holes along the body of the instrument and these included the cornett, serpent, ophicleide, keyed bugle and keyed trumpet. They are more difficult to play than valved instruments, Brass instruments may also be characterised by two generalizations about geometry of the bore, that is, the tubing between the mouthpiece and the flaring of the tubing into the bell. Those two generalizations are with regard to the degree of taper or conicity of the bore and the diameter of the bore with respect to its length, cylindrical bore brass instruments are generally perceived as having a brighter, more penetrating tone quality compared to conical bore brass instruments. The trumpet, baritone horn and all trombones are cylindrical bore, in particular, the slide design of the trombone necessitates this. Conical bore brass instruments are those in which tubing of constantly increasing diameter predominates, conical bore instruments are generally perceived as having a more mellow tone quality than the cylindrical bore brass instruments. The British brass band group of instruments fall into this category and this includes the flugelhorn, cornet, tenor horn, horn, euphonium and tuba

20.
Woodwind instrument
–
Woodwind instruments are a family of musical instruments within the more general category of wind instruments. There are two types of woodwind instruments, flutes and reed instruments. What differentiates these instruments from other instruments is the way in which they produce their sound. Examples are a saxophone, a bassoon and a piccolo, flutes produce sound by directing a focused stream of air below the edge of a hole in a cylindrical tube. The flute family can be divided into two sub-families, open flutes and closed flutes, to produce a sound with an open flute, the player is required to blow a stream of air across a sharp edge that then splits the airstream. This split airstream then acts upon the air contained within the flutes hollow causing it to vibrate. Examples of open flutes are the flute, panpipes and shakuhachi. Ancient flutes of this variety were often made from sections of plants such as grasses, reeds. Later, flutes were made of such as tin, copper. Modern concert flutes are made of high-grade metal alloys, usually containing nickel, silver, copper. To produce a sound with a flute, the player is required to blow air into a duct. This duct acts as a channel bringing the air to a sharp edge, as with the open flutes, the air is then split, this causes the column of air within the closed flute to vibrate and produce sound. Examples of this type of include the recorder, ocarina. Reed instruments produce sound by focusing air into a mouthpiece which then causes a reed, or reeds, similar to flutes, Reed pipes are also further divided into two types, single reed and double reed. Single-reed woodwinds produce sound by placing a reed onto the opening of a mouthpiece, when air is forced between the reed and the mouthpiece, the reed causes the air column in the instrument to vibrate and produce its unique sound. Single reed instruments include the clarinet, saxophone, and others such as the chalumeau, double-reed instruments use two precisely cut, small pieces of cane bound together at the base. This form of production has been estimated to have originated in the middle to late Neolithic period. The finished, bound reed is inserted into the instrument and vibrates as air is forced between the two pieces and this family of reed pipes is subdivided further into another two sub-families, exposed double reed, and capped double reed instruments

21.
Percussion instrument
–
A percussion instrument is a musical instrument that is sounded by being struck or scraped by a beater, struck, scraped or rubbed by hand, or struck against another similar instrument. The percussion family is believed to include the oldest musical instruments, the percussion section of an orchestra most commonly contains instruments such as timpani, snare drum, bass drum, cymbals, triangle and tambourine. However, the section can also contain non-percussive instruments, such as whistles and sirens, percussive techniques can also be applied to the human body, as in body percussion. On the other hand, keyboard instruments, such as the celesta, are not normally part of the percussion section, Percussion instruments may play not only rhythm, but also melody and harmony. Percussion is commonly referred to as the backbone or the heartbeat of an ensemble, often working in close collaboration with bass instruments. In jazz and other popular ensembles, the pianist, bassist, drummer. Most classical pieces written for full orchestra since the time of Haydn and Mozart are orchestrated to place emphasis on the strings, woodwinds, however, often at least one pair of timpani is included, though they rarely play continuously. Rather, they serve to provide additional accents when needed, in the 18th and 19th centuries, other percussion instruments have been used, again generally sparingly. The use of percussion instruments became more frequent in the 20th century classical music, in almost every style of music, percussion plays a pivotal role. In classic jazz, one almost immediately thinks of the rhythm of the hi-hats or the ride cymbal when the word swing is spoken. Because of the diversity of instruments, it is not uncommon to find large musical ensembles composed entirely of percussion. Rhythm, melody, and harmony are all represented in these ensembles, music for pitched percussion instruments can be notated on a staff with the same treble and bass clefs used by many non-percussive instruments. Music for percussive instruments without a pitch can be notated with a specialist rhythm or percussion-clef. The word percussion has evolved from Latin terms, percussio, as a noun in contemporary English it is described in Wiktionary as the collision of two bodies to produce a sound. Hornbostel–Sachs has no high-level section for percussion, Most percussion instruments are classified as idiophones and membranophones.1 Concussion idiophones or clappers, played in pairs and beaten against each other, such as zills and clapsticks. 111.2 Percussion idiophones, includes many percussion instruments played with the hand or by a mallet, such as the hang, gongs and the xylophone. 21 Struck drums, includes most types of drum, such as the timpani, snare drum, (Included in most drum sets or 412. Stringed instruments played with such as the hammered dulcimer

Concert band
–
On rare occasions, additional non traditional instruments may be added to such ensembles such as piano, harp, synthesizer, or electric guitar. A concert bands repertoire includes original compositions, transcriptions/arrangements of orchestral compositions, light music. Though the instrumentation is similar, a band is distinguished from the marching band in that its primary function is as a concert ensemble. The standard repertoire for the band does, however, contain concert marches. One notable and influential original symphonic work for band was Gustav Holsts First Suite in E-Flat, written in 1909, following Holst, a variety of British, American, Canadian and Australian composers wrote for the medium, including Percy Grainger, James Swearingen and Ralph Vaughan Williams. The wind ensemble could be said to be modeled on the section of a Wagner orchestra. While many people consider the ensemble to be one player on a part. Full band pieces usually require doubling or tripling of the clarinet parts, according to Fennell, the wind ensemble was not revolutionary, but developed naturally out of the music that led him to the concept. Professional concert bands not associated with the military are rare, lesbian & Gay Big Apple Corps, New York, New York, conducted by Kelly Watkins Municipal Band of Charlottesville, Inc. Other large competitions include the World Music Competition, held in the Netherlands, instrumentation for the wind band is not standardized, composers will frequently add or omit parts. Instrumentation differs depending on the type of ensemble, middle and high school bands frequently have more limited instrumentation and fewer parts. This is both to limit the difficulty for inexperienced players and because schools frequently do not have access to the common instruments. The standard concert band will have several players on each part, depending on available personnel, a concert band can theoretically have as many as 200 members from a set of only 35 parts. Also, it is common to see two tubas playing the part in a wind ensemble. Complicated percussion parts are common in concert pieces, often requiring many percussionists. Many believe this is a difference between the orchestra—which usually lacks a large battery of percussion—and the concert band. While in older transcriptions and concert works, the timpani were treated as its own section as in the orchestra, today, in bands, consequently, the timpani player often will double on other percussion instruments. Contemporary compositions often call on players to use unusual instruments or effects, for example, several pieces call on the use of a siren while others will ask players to play recorders, a glass harmonica, or to sing

Saxophone
–
The saxophone is a family of woodwind instruments. Saxophones are usually made of brass and played with a single-reed mouthpiece similar to that of the clarinet, the saxophone family was invented by the Belgian instrument maker Adolphe Sax in 1840. He patented the saxophone on June 28,1846, in two groups of seven instruments each, each series consisted of instruments of various sizes in alternating transposition. The series pitched in B♭ and E♭, designed for bands, have proved extremely popular. The saxophone is used in music, military bands, marching bands. The saxophone was developed in 1846 by Adolphe Sax, a Belgian instrument maker, flautist, born in Dinant and originally based in Brussels, he moved to Paris in 1842 to establish his musical instrument business. Prior to his work on the saxophone, he had several improvements to the bass clarinet by improving its keywork and acoustics. Sax was also a maker of the ophicleide, a large conical brass instrument in the bass register with keys similar to a woodwind instrument. His experience with two instruments allowed him to develop the skills and technologies needed to make the first saxophones. As an outgrowth of his work improving the bass clarinet, Sax began developing an instrument with the projection of a brass instrument and he wanted it to overblow at the octave, unlike the clarinet, which rises in pitch by a twelfth when overblown. An instrument that overblows at the octave has identical fingering for both registers, Sax created an instrument with a single-reed mouthpiece like a clarinet, conical brass body like an ophicleide, and some acoustic properties of both the horn and the clarinet. Having constructed saxophones in several sizes in the early 1840s, Sax applied for, and received, the patent encompassed 14 versions of the fundamental design, split into two categories of seven instruments each, and ranging from sopranino to contrabass. Although the instruments transposed at either F or C have been considered orchestral, the C soprano saxophone was the only instrument to sound at concert pitch. Saxs patent expired in 1866, thereafter, numerous saxophonists and instrument manufacturers implemented their own improvements to the design, the first substantial modification was by a French manufacturer who extended the bell slightly and added an extra key to extend the range downwards by one semitone to B♭. It is suspected that Sax himself may have attempted this modification and this extension is now commonplace in almost all modern designs, along with other minor changes such as added keys for alternate fingerings. Using alternate fingerings allows a player to play faster and more easily, a player may also use alternate fingerings to bend the pitch. Some of the alternate fingerings are good for trilling, scales, a substantial advancement in saxophone keywork was the development of a method by which the left thumb operates both tone holes with a single octave key, which is now universal on modern saxophones. This enables a chromatic scale to be played two octaves simply by playing the diatonic scale combined with alternately raising and lowering this one digit

Trumpet
–
A trumpet is a musical instrument commonly used in classical and jazz ensembles. The trumpet group contains the instruments with the highest register in the brass family, trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through almost-closed lips, producing a sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, there are many distinct types of trumpet, with the most common being pitched in B♭, having a tubing length of about 1.48 m. Early trumpets did not provide means to change the length of tubing, most trumpets have valves of the piston type, while some have the rotary type. The use of rotary-valved trumpets is more common in orchestral settings, each valve, when engaged, increases the length of tubing, lowering the pitch of the instrument. A musician who plays the trumpet is called a trumpet player or trumpeter, the earliest trumpets date back to 1500 BC and earlier. The bronze and silver trumpets from Tutankhamuns grave in Egypt, bronze lurs from Scandinavia, trumpets from the Oxus civilization of Central Asia have decorated swellings in the middle, yet are made out of one sheet of metal, which is considered a technical wonder. The Shofar, made from a ram horn and the Hatzotzeroth and they were played in Solomons Temple around 3000 years ago. They were said to be used to blow down the walls of Jericho and they are still used on certain religious days. The Salpinx was a straight trumpet 62 inches long, made of bone or bronze, Salpinx contests were a part of the original Olympic Games. The Moche people of ancient Peru depicted trumpets in their art going back to AD300, the earliest trumpets were signaling instruments used for military or religious purposes, rather than music in the modern sense, and the modern bugle continues this signaling tradition. Improvements to instrument design and metal making in the late Middle Ages, the natural trumpets of this era consisted of a single coiled tube without valves and therefore could only produce the notes of a single overtone series. Changing keys required the player to change crooks of the instrument, the development of the upper, clarino register by specialist trumpeters—notably Cesare Bendinelli—would lend itself well to the Baroque era, also known as the Golden Age of the natural trumpet. During this period, a vast body of music was written for virtuoso trumpeters, the art was revived in the mid-20th century and natural trumpet playing is again a thriving art around the world. The melody-dominated homophony of the classical and romantic periods relegated the trumpet to a role by most major composers owing to the limitations of the natural trumpet. Berlioz wrote in 1844, Notwithstanding the real loftiness and distinguished nature of its quality of tone, there are few instruments that have been more degraded. The attempt to give the trumpet more chromatic freedom in its range saw the development of the keyed trumpet, the symphonies of Mozart, Beethoven, and as late as Brahms, were still played on natural trumpets

Electric guitar
–
The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by a guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker. The output of a guitar is an electric signal. Invented in 1931, the electric guitar was adopted by jazz guitarists. Early proponents of the guitar on record included Les Paul, Lonnie Johnson, Sister Rosetta Tharpe, T-Bone Walker. During the 1950s and 1960s, the guitar became the most important instrument in pop music. It has evolved into an instrument that is capable of a multitude of sounds and styles in genres ranging from pop and rock to country music, blues and jazz. It served as a component in the development of electric blues, rock and roll, rock music, heavy metal music. Electric guitar design and construction vary greatly in the shape of the body and the configuration of the neck, bridge, Guitars may have a fixed bridge or a spring-loaded hinged bridge that lets players bend the pitch of notes or chords up or down or perform vibrato effects. The sound of a guitar can be modified by new playing techniques such as string bending, tapping, hammering on, using audio feedback, in a small group, such as a power trio, one guitarist switches between both roles. In larger rock and metal bands, there is often a rhythm guitarist, many experiments at electrically amplifying the vibrations of a string instrument were made dating back to the early part of the 20th century. Patents from the 1910s show telephone transmitters were adapted and placed inside violins, hobbyists in the 1920s used carbon button microphones attached to the bridge, however, these detected vibration from the bridge on top of the instrument, resulting in a weak signal. With numerous people experimenting with electrical instruments in the 1920s and early 1930s, Electric guitars were originally designed by acoustic guitar makers and instrument manufacturers. Some of the earliest electric guitars adapted hollow-bodied acoustic instruments and used tungsten pickups, the first electrically amplified guitar was designed in 1931 by George Beauchamp, the general manager of the National Guitar Corporation, with Paul Barth, who was vice president. The maple body prototype for the one-piece cast aluminum frying pan was built by Harry Watson, commercial production began in late summer of 1932 by the Ro-Pat-In Corporation, in Los Angeles, a partnership of Beauchamp, Adolph Rickenbacker, and Paul Barth. In 1934, the company was renamed the Rickenbacker Electro Stringed Instrument Company, in that year Beauchamp applied for a United States patent for an Electrical Stringed Musical Instrument and the patent was issued in 1937. The Electro-Spanish Ken Roberts provided players a full 25 scale, with 17 frets free of the fretboard and it is estimated that fewer than 50 Electro-Spanish Ken Roberts were constructed between 1933 and 1937, fewer than 10 are known to survive today. The need for the guitar became apparent during the big band era as orchestras increased in size, particularly when acoustic guitars had to compete with large

Hammond organ
–
The Hammond organ is an electric organ, invented by Laurens Hammond and John M. Hanert and first manufactured in 1935. Various models have been produced, most of use sliding drawbars to create a variety of sounds. Around two million Hammond organs have been manufactured, the organ is commonly used with, and associated with, the Leslie speaker. The organ was originally marketed and sold by the Hammond Organ Company to churches as a lower-cost alternative to the pipe organ. It quickly became popular with jazz musicians in organ trios. Organ trios were hired by jazz club owners, who found that organ trios were a cheaper alternative to hiring a big band. The Hammond Organ Company struggled financially during the 1970s as they abandoned tonewheel organs and these instruments were not as popular with musicians as the tonewheels had been, and the company went out of business in 1985. The Hammond name was purchased by the Suzuki Musical Instrument Corporation and this culminated in the production of the New B-3 in 2002, which provided an accurate recreation of the original B-3 organ using modern digital technology. Hammond-Suzuki continues to manufacture a variety of organs for both players and churches. Other companies, such as Korg, Roland and Clavia, have achieved success in providing emulations of the original tonewheel organs. The sound of a tonewheel Hammond can also be emulated using software such as Native Instruments B4. A number of distinctive Hammond organ features are not usually found on other keyboards like the piano or synthesizer, Some are similar to a pipe organ, but others are unique to the instrument. Most Hammond organs have two 61-note keyboards called manuals, as with pipe organ keyboards, the two manuals are arrayed on two levels close to each other. There is no difference in volume regardless of how heavily or lightly the key is pressed, the keys on each manual have a lightweight action, which allows players to perform rapid passages more easily than on a piano. In contrast to piano and pipe organ keys, Hammond keys have a flat-front profile, Early Hammond console models had sharp edges, but starting with the B-2 these were rounded, as they were cheaper to manufacture. The M series of spinets also had waterfall keys, but later models had diving board style keys which resembled those found on a church organ. Modern Hammond-Suzuki models use waterfall keys, Hammond console organs come with a wooden pedalboard played with the feet, for bass notes. Most console Hammond pedalboards have 25 notes, with the note a low C

Bass guitar
–
The bass guitar is a stringed instrument played primarily with the fingers or thumb, by plucking, slapping, popping, strumming, tapping, thumping, or picking with a plectrum, often known as a pick. The bass guitar is similar in appearance and construction to a guitar, but with a longer neck and scale length. The four-string bass, by far the most common, is tuned the same as the double bass. The bass guitar is an instrument, as it is notated in bass clef an octave higher than it sounds to avoid excessive ledger lines. Like the electric guitar, the guitar has pickups and it is plugged into an amplifier and speaker on stage, or into a larger PA system using a DI unit. Since the 1960s, the guitar has largely replaced the double bass in popular music as the bass instrument in the rhythm section. While types of basslines vary widely from one style of music to another, many styles of music utilise the bass guitar, including rock, heavy metal, pop, punk rock, country, reggae, gospel, blues, symphonic rock, and jazz. It is often a solo instrument in jazz, jazz fusion, Latin, funk, progressive rock and other rock, the adoption of a guitar form made the instrument easier to hold and transport than any of the existing stringed bass instruments. The addition of frets enabled bassists to play in more easily than on acoustic or electric upright basses. Around 100 of these instruments were made during this period, around 1947, Tutmarcs son, Bud, began marketing a similar bass under the Serenader brand name, prominently advertised in the nationally distributed L. D. Heater Music Company wholesale jobber catalogue of 1948, however, the Tutmarc family inventions did not achieve market success. In the 1950s, Leo Fender, with the help of his employee George Fullerton and his Fender Precision Bass, which began production in October 1951, became a widely copied industry standard. This split pickup, introduced in 1957, appears to have been two mandolin pickups, the pole pieces and leads of the coils were reversed with respect to each other, producing a humbucking effect. Humbucking is a design that electrically cancels the effect of any AC hum, the Fender Bass was a revolutionary new instrument, which could be easily transported, and which was less prone to feedback when amplified than acoustic bass instruments. Monk Montgomery was the first bass player to tour with the Fender bass guitar, roy Johnson, and Shifty Henry with Louis Jordan & His Tympany Five, were other early Fender bass pioneers. Bill Black, playing with Elvis Presley, switched from bass to the Fender Precision Bass around 1957. The bass guitar was intended to appeal to guitarists as well as upright bass players, following Fenders lead, in 1953, Gibson released the first short scale violin-shaped electric bass with extendable end pin, allowing it to be played upright or horizontally. In 1959 these were followed by the more conventional-looking EB-0 Bass, the EB-0 was very similar to a Gibson SG in appearance

Double bass
–
The double bass, or simply the bass, is the largest and lowest-pitched bowed string instrument in the modern symphony orchestra. It is an instrument and is typically notated one octave higher than sounding to avoid excessive ledger lines below the staff. The double bass is the modern bowed string instrument that is tuned in fourths, rather than fifths, with strings usually tuned to E1, A1, D2. The instruments exact lineage is still a matter of some debate, the double bass is a standard member of the orchestras string section, as well as the concert band, and is featured in concertos, solo and chamber music in Western classical music. The bass is used in a range of genres, such as jazz, 1950s-style blues and rock and roll, rockabilly, psychobilly, traditional country music, bluegrass, tango. The double bass is played either with a bow or by plucking the strings, in orchestral repertoire and tango music, both arco and pizzicato are employed. In jazz, blues, and rockabilly, pizzicato is the norm, Classical music uses just the natural sound produced acoustically by the instrument, so does traditional bluegrass. In jazz, blues, and related genres, the bass is typically amplified with an amplifier and speaker, the double bass stands around 180 cm from scroll to endpin. However, other sizes are available, such as a 1⁄2 or 3⁄4 and these sizes do not reflect the size relative to a full size, or 4⁄4 bass, a 1⁄2 bass is not half the size of a bass but is only slightly smaller. It is typically constructed from several types of wood, including maple for the back, spruce for the top and it is uncertain whether the instrument is a descendant of the viola da gamba or of the violin, but it is traditionally aligned with the violin family. While the double bass is nearly identical in construction to other violin family instruments, like other violin and viol-family string instruments, the double bass is played either with a bow or by plucking the strings. In orchestral repertoire and tango music, both arco and pizzicato are employed, in jazz, blues, and rockabilly, pizzicato is the norm, except for some solos and also occasional written parts in modern jazz that call for bowing. In classical pedagogy, almost all of the focus is on performing with the bow and producing a good bowed tone, some of these articulations can be combined, for example, the combination of sul ponticello and tremolo can produce eerie, ghostly sounds. Classical bass players do play pizzicato parts in orchestra, but these parts generally require simple notes, vibrato is used to add expression to string playing. In general, very loud, low-register passages are played with little or no vibrato, mid- and higher-register melodies are typically played with more vibrato. The speed and intensity of the vibrato is varied by the performer for an emotional and musical effect, in jazz, rockabilly and other related genres, much or all of the focus is on playing pizzicato. In jazz and jump blues, bassists are required to play extremely rapid pizzicato walking basslines for extended periods, as well, jazz and rockabilly bassists develop virtuoso pizzicato techniques that enable them to play rapid solos that incorporate fast-moving triplet and sixteenth note figures. In jazz and related styles, bassists often add semi-percussive ghost notes into basslines, to add to the rhythmic feel and to add fills to a bassline

Synthesizer
–
A synthesizer is an electronic musical instrument that generates electric signals that are converted to sound through instrument amplifiers and loudspeakers or headphones. Synthesizers may either imitate instruments like piano, Hammond organ, flute, vocals, natural sounds like ocean waves, etc. or generate new electronic timbres. Synthesizers without built-in controllers are called sound modules, and are controlled via USB, MIDI or CV/gate using a controller device. Synthesizers use various methods to generate electronic signals, synthesizers were first used in pop music in the 1960s. In the 1970s, synths were used in disco, especially in the late 1970s, in the 1980s, the invention of the relatively inexpensive, mass market Yamaha DX7 synth made synthesizers widely available. 1980s pop and dance music often made use of synthesizers. In the 2010s, synthesizers are used in genres of pop, rock. Contemporary classical music composers from the 20th and 21st century write compositions for synthesizer, the beginnings of the synthesizer are difficult to trace, as it is difficult to draw a distinction between synthesizers and some early electric or electronic musical instruments. One of the earliest electric musical instruments, the telegraph, was invented in 1876 by American electrical engineer Elisha Gray. He accidentally discovered the sound generation from a self-vibrating electromechanical circuit and this musical telegraph used steel reeds with oscillations created by electromagnets transmitted over a telegraph line. Gray also built a simple loudspeaker device into later models, consisting of a diaphragm in a magnetic field. This instrument was a remote electromechanical musical instrument that used telegraphy, though it lacked an arbitrary sound-synthesis function, some have erroneously called it the first synthesizer. In 1897, Thaddeus Cahill invented the Teleharmonium, which used dynamos, and was capable of additive synthesis like the Hammond organ, however, Cahills business was unsuccessful for various reasons, and similar but more compact instruments were subsequently developed, such as electronic and tonewheel organs. In 1906, American engineer, Lee De Forest ushered in the electronics age and he invented the first amplifying vacuum tube, called the Audion tube. This led to new entertainment technologies, including radio and sound films, ondes Martenot and Trautonium were continuously developed for several decades, finally developing qualities similar to later synthesizers. In the 1920s, Arseny Avraamov developed various systems of graphic sonic art, in 1938, USSR engineer Yevgeny Murzin designed a compositional tool called ANS, one of the earliest real-time additive synthesizers using optoelectronics. The earliest polyphonic synthesizers were developed in Germany and the United States, during the three years that Hammond manufactured this model,1,069 units were shipped, but production was discontinued at the start of World War II. Both instruments were the forerunners of the electronic organs and polyphonic synthesizers

Rhythm section
–
Many of the rhythm section instruments, such as keyboard instruments and guitars, are also used to play the chord progression upon which the song is based. The bass instrument plays the bassline that supports the chord progression. The term is common in small musical ensembles, such as bands that play jazz, country, blues. In modern rock music, a rhythm guitarist specializes in rhythmic and chordal playing, often repeating quaver, in the louder genres, such as hard rock, heavy metal and punk rock, rhythm guitarists often play power chords with distortion. Rhythm guitarists often strum open chords in pop, rock, country and folk music and play barre chords in many pop, a typical rhythm section comprises one or more guitars, and/or a keyboard instrument a double bass or electric bass, and drums. In some styles of music, there may be additional percussionists playing instruments such as the djembe or shakers, some styles of music often have two electric guitarists, such as rock genres like heavy metal music and punk rock. Some styles of music use multiple keyboard instrument performers simultaneously for a fuller sound, the instrumentalists used in a rhythm section vary according to the style of music and era. Modern pop, rock and jazz band rhythm sections typically consist of a drummer, a bass player, the term rhythm section may also refer to the instruments in this group. In music industry parlance, the amplifiers and some of the instruments are nicknamed the backline, backline instruments are commonly provided for bands at music festivals and other concerts where several bands will play during an event. By providing these backline instruments, this speeds up the process when new bands take the stage. Even when a venue or festival provides a backline, musicians must still supply some instruments themselves, such as guitars, a bass, and, in some cases. Although rhythm sections spend much of the time providing accompaniment for songs, in some cases, in some songs or styles of music, instruments from the rhythm section may play soloistic roles on occasion or play a melodic role. However, since rhythm sections provide the underpinning for a performance by the lead instruments and vocalists. Some of the most accomplished rhythm sections have become famous, such as The Band, The E Street Band and Sly Dunbar, as well, in some popular bands, all of the band members, including rhythm section members, have become famous as individuals. In each style of music, there are different musical approaches and styles that rhythm section members are expected to use, drummers and percussionists are expected to be able to improvise or prepare rhythm parts that suit the style of a given song. In some cases, an arranger, orchestrator or composer will provide a bass part or drum part written in music notation. Rhythm section members may be expected to sing backup vocals or harmony parts in some styles of music, in some types of heavy metal music, rhythm section members may be expected to be able to headbang while performing. Less commonly, some rhythm section members may sing lead vocals, in some groups, one rhythm section member may have other roles, such as bandleader, conductor, songwriter, composer or arranger

Drum kit
–
A drum kit consists of a mix of drums and idiophones most significantly cymbals but also including the woodblock and cowbell. In the 2000s, some also include electronic instruments and both hybrid and entirely electronic kits are used. If some or all of them are replaced by electronic drums, the drum kit is usually played while seated on a drum stool or throne. The drum kit differs from instruments that can be used to produce pitched melodies or chords, even though drums are often placed musically alongside others that do, such as the piano or guitar. The drum kit is part of the rhythm section used in many types of popular and traditional music styles ranging from rock and pop to blues. Other standard instruments used in the section include the electric bass, electric guitar. Many drummers extend their kits from this pattern, adding more drums, more cymbals. Some performers, such as some rockabilly drummers, use small kits that omit elements from the basic setup, some drum kit players may have other roles in the band, such as providing backup vocals, or less commonly, lead vocals. Thus, in an early 1800s orchestra piece, if the called for bass drum, triangle and cymbals. In the 1840s, percussionists began to experiment with foot pedals as a way to them to play more than one instrument. In the 1860s, percussionists started combining multiple drums into a set, the bass drum, snare drum, cymbals, and other percussion instruments were all played using hand-held drum sticks. Double-drumming was developed to one person to play the bass and snare with sticks. With this approach, the drum was usually played on beats one. This resulted in a swing and dance feel. The drum set was referred to as a trap set. By the 1870s, drummers were using an overhang pedal, most drummers in the 1870s preferred to do double drumming without any pedal to play multiple drums, rather than use an overhang pedal. Companies patented their pedal systems such as Dee Dee Chandler of New Orleans 1904–05, liberating the hands for the first time, this evolution saw the bass drum played with the foot of a standing percussionist. The bass drum became the central piece around which every other percussion instrument would later revolve and it was the golden age of drum building for many famous drum companies, with Ludwig introducing

Conducting
–
Conducting is the art of directing a musical performance, such as an orchestral or choral concert. A conductors directions will almost invariably be supplemented or reinforced by verbal instructions or suggestions to their musicians in rehearsal prior to a performance. The conductor typically stands on a podium with a large music stand for the full score. Conducting while playing a piano or synthesizer may also be done with musical theatre pit orchestras, communication is typically non-verbal during a performance. However, in rehearsals, frequent interruptions allow the conductor to give verbal directions as to how the music should be played or sung, Conductors act as guides to the orchestras or choirs they conduct. They choose the works to be performed and study their scores, to which they may make adjustments, work out their interpretation. They may also attend to matters, such as scheduling rehearsals, planning a concert season, hearing auditions and selecting members. Orchestras, choirs, concert bands and other musical ensembles such as big bands are usually led by conductors. The principal conductor of an orchestra or opera company is referred to as a music director or chief conductor, or by the German words Kapellmeister or Dirigent. Conductors of choirs or choruses are sometimes referred to as director, chorus master, or choirmaster. Conductors of concert bands, military bands, marching bands and other bands may hold the title of director, bandmaster. Respected senior conductors are sometimes referred to by the Italian word, an early form of conducting is cheironomy, the use of hand gestures to indicate melodic shape. This has been practiced at least as far back as the Middle Ages, in the 17th century, other devices to indicate the passing of time came into use. Rolled up sheets of paper, smaller sticks and unadorned hands are all shown in pictures from this period, the large staff was responsible for the death of Jean-Baptiste Lully, who injured his foot with one while conducting a Te Deum for the Kings recovery from illness. The wound became gangrenous and Lully refused amputation, whereupon the gangrene spread to his leg, in instrumental music throughout the 18th century, a member of the ensemble usually acted as the conductor. This was sometimes the concertmaster, who could use his bow as a baton and it was common to conduct from the harpsichord in pieces that had a basso continuo part. In opera performances, there were sometimes two conductors – the keyboard player was in charge of the singers, and the principal violinist or leader was in charge of the orchestra. By the early 19th century, it became the norm to have a dedicated conductor, the size of the usual orchestra expanded during this period, and the use of a baton became more common, as it was easier to see than bare hands or rolled-up paper

33.
Concertmaster
–
The Concertmaster is the second-most significant person in an orchestra, symphonic band or other musical ensemble after the conductor or director. Another common term in the U. S. is First Chair, in the U. K. the term commonly used is leader. In an orchestra, the concertmaster is the leader of the first violin section, there is another violin section, the second violins, led by the principal second violin. Any violin solo in a work is played by the concertmaster. The concertmaster sits to the left, closest to the audience, in what is called the first chair. The concertmaster makes decisions regarding bowing and other details of violin playing for the violins. He or she leads the orchestra in tuning before concerts and rehearsals, leading the orchestral tuning is not just a mere formality, if the concertmaster believes that a section is not adequately tuned, he or she will signal to the oboe player to play another A. Several larger orchestras have one or more assistant concertmasters, who lead the orchestra in the concertmasters absence, the concertmaster, along with the conductor and section principals, will normally participate in the auditions of important musicians in the orchestra. The concertmaster in a concert band is the principal clarinet, oboe, flute or saxophone. The first-chair clarinet concertmaster will, in practice, play all solos for their instrument. Often the lead flautist will receive similar responsibilities to the concertmaster, depending on several factors such as age, skill. The concertmaster will, in orchestral and wind band settings, also coordinate with other principals and section leaders, in most cases being their senior in terms of group pecking order. In brass bands, the role of concertmaster is often filled by the solo cornet or trumpet. The duties and tasks of the concertmaster are myriad, primarily, he or she acts as the conduit between conductor and orchestra and is accountable to both parties. One of the tasks of the concertmaster is to provide bowings for the 1st violins prior to rehearsal. This entails a great knowledge of playing styles in addition to complete idiomatic understanding of the mechanics of string playing. Ensemble cohesion emanates directly from the contact and connection between these vital front desk positions, the concertmaster assumes responsibility for the tone and execution of the entire section of 1st violins, in addition to performing any solo passages that occur in a given piece. Another primary duty of the concertmaster is to translate instructions from the conductor into specific technical language for the strings, full-time professional orchestras work with several conductors through the course of a regular season

Jazz
–
Jazz is a music genre that originated amongst African Americans in New Orleans, United States, in the late 19th and early 20th centuries, and developed from roots in Blues and Ragtime. Since the 1920s jazz age, jazz has become recognized as a form of musical expression. Jazz is characterized by swing and blue notes, call and response vocals, polyrhythms, Jazz has roots in West African cultural and musical expression, and in African-American music traditions including blues and ragtime, as well as European military band music. Although the foundation of jazz is deeply rooted within the Black experience of the United States, different cultures have contributed their own experience, intellectuals around the world have hailed jazz as one of Americas original art forms. As jazz spread around the world, it drew on different national, regional, and local musical cultures, New Orleans jazz began in the early 1910s, combining earlier brass-band marches, French quadrilles, biguine, ragtime and blues with collective polyphonic improvisation. In the 1930s, heavily arranged dance-oriented swing big bands, Kansas City jazz, bebop emerged in the 1940s, shifting jazz from danceable popular music toward a more challenging musicians music which was played at faster tempos and used more chord-based improvisation. Cool jazz developed in the end of the 1940s, introducing calmer, smoother sounds and long, modal jazz developed in the late 1950s, using the mode, or musical scale, as the basis of musical structure and improvisation. Jazz-rock fusion appeared in the late 1960s and early 1970s, combining jazz improvisation with rock rhythms, electric instruments. In the early 1980s, a form of jazz fusion called smooth jazz became successful. Other styles and genres abound in the 2000s, such as Latin, the question of the origin of the word jazz has resulted in considerable research, and its history is well documented. It is believed to be related to jasm, a term dating back to 1860 meaning pep. The use of the word in a context was documented as early as 1915 in the Chicago Daily Tribune. Its first documented use in a context in New Orleans was in a November 14,1916 Times-Picayune article about jas bands. In an interview with NPR, musician Eubie Blake offered his recollections of the slang connotations of the term, saying, When Broadway picked it up. That was dirty, and if you knew what it was, the American Dialect Society named it the Word of the Twentieth Century. Jazz has proved to be difficult to define, since it encompasses such a wide range of music spanning a period of over 100 years. Attempts have been made to define jazz from the perspective of other musical traditions, in the opinion of Robert Christgau, most of us would say that inventing meaning while letting loose is the essence and promise of jazz. As Duke Ellington, one of jazzs most famous figures, said, although jazz is considered highly difficult to define, at least in part because it contains so many varied subgenres, improvisation is consistently regarded as being one of its key elements

Big band
–
A big band is a type of musical ensemble associated with playing jazz music and which became popular during the Swing Era from the early 1930s until the late 1940s. Big Bands evolved with the times and continue to this day, a big band typically consists of approximately 12 to 25 musicians and contains saxophones, trumpets, trombones, and a rhythm section. The terms jazz band, jazz ensemble, stage band, jazz orchestra and this does not, however, mean that each one of these names is technically correct for naming a big band specifically. The music is traditionally called charts, improvised solos may be played only when called for by the arranger. There are two periods in the history of popular bands. Beginning in the mid-1920s, big bands, then consisting of 10–25 pieces. At that time they played a form of jazz that involved very little improvisation, which included a string section with violins. A few bands also had violas and cellos, usually one or two along with them, the dance form of jazz was characterized by a sweet and romantic melody. Orchestras tended to stick to the melody as it was written and vocals would be sung, many of these artists changed styles or retired after the introduction of swing music. Although unashamedly commercial, these bands often featured front-rank jazz musicians - for example Paul Whiteman employed Bix Beiderbecke, there were also all-girl bands such as Helen Lewis and Her All-Girl Jazz Syncopators. Towards the end of the 1920s, a new form of Big Band emerged which was more authentically jazz and this form of music never gained the popularity of the sweet dance form of jazz. The few recordings made in form of jazz were labelled race records and were intended for a limited urban audience. Few white musicians were familiar with music, Johnny Mercer. The three major centres in this development were New York City, Chicago and Kansas City, some big ensembles, like the Joe King Oliver outfit played a kind of half arranged, half improvised jazz, often relying on head arrangements. Other great bands, like the one of Luis Russell became a vehicle for star instrumentalists, there the whole arrangement had to promote all the possibilities of the star, although they often contained very good musicians, like Henry Red Allen, J. C. Earl Hines became the star of Chicago with his Grand Terrace Cafe band, meanwhile, in Kansas City and across the Southwest, an earthier, bluesier style was developed by such bandleaders as Benny Moten and, later, by Jay McShann and Jesse Stone. Radio was a factor in gaining notice and fame for Benny Goodman. Soon, others challenged him, and the battles of the bands became a staple at theater performances featuring many groups on one bill

Horn section
–
A horn section is a group of musicians playing horns. In an orchestra or concert band, it refers to the musicians who play the French horn, in many popular-music genres the term is applied loosely to any group of woodwind or brass instruments, or a combination of woodwinds and brass. In a symphony orchestra, the section is the group of symphonic musicians who play the French horn. These musicians are typically seated to the back of the ensemble, placing them to the left with their bells toward the audience increases the prominence of the section, whereas on the right, the sound reflects off the back of the stage. The order from the horn to the fourth horn is right to left from the directors view. The section is ordered in this way so the horn may be heard by all players, as the principal sets the timbre. The horn section usually has parts which are prepared by an arranger using orchestration to provide a harmonic and melodic accompaniment to a song or musical group. In some cases, the section may improvise a simple backing part using well-known stock lines. Horn sections are a part of musical genres such as jazz, R&B, blues, funk, calypso, ska, soul music. Most of these horn sections feature some combination of saxophones, trumpets, more rarely, other wind or brass instruments such as flute, clarinet or tuba may be added. Other popular musical genres, such as rock and pop, also use horn sections, horn sections in blues bands and funk groups may be composed of session musicians playing arranged parts, or they may be a consistent group of musicians. A small number of horn sections use a consistent group of musicians who become known as a unit. Grove Dictionary of Musical Instruments, Oxford Music Online

Kneisel Quartet
–
The Kneisel Quartet was a string quartet musical ensemble established in Boston, in the U. S. state of Massachusetts in 1885. It existed until 1917, and in its time became recognised as the string quartet in the United States. The quartet remained settled at Boston, performing at such as Chickering Hall. In January 1894 It gave the premiere in Boston and second performance in New York of Dvořáks American String Quartet, in 1903 the quartets operational base moved to New York City. It ceased activity in 1917 owing to the demand of teaching upon Kneisels time. The farewell concert was given on 3 April 1917 in New York, charles Ives considered a certain performance by the Kneisel Quartet effeminate, and he was inspired to write a more virile quartet, which became his String Quartet No.2.

Iran
–
Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Chamber music
–
Chamber music is a form of classical music that is composed for a small group of instruments—traditionally a group that could fit in a palace chamber or a large room. Most broadly, it includes any art music that is performed by a number of performers. However, by convention, it usually does not include solo instrument performances, because of its intimate nature, chamber music has been described as the music of friends. Playing chamber music requires special skills, both musical and social, that differ from the skills required for playing solo or symphonic works, Johann Wolfgang von Goethe described chamber music as four rational people conversing. The analogy to conversation recurs in descriptions and analyses of chamber music compositions, from its earliest beginnings in the Medieval period to the present, chamber music has been a reflection of the changes in the technology and the society that produced it. During the Middle Ages and the early Renaissance, instruments were used primarily as accompaniment for singers, String players would play along with the melody line sung by the singer. There were also purely instrumental ensembles, often of stringed precursors of the violin family, some analysts consider the origin of classical instrumental ensembles to be the sonata da camera and the sonata da chiesa. These were compositions for one to five or more instruments, the sonata da camera was a suite of slow and fast movements, interspersed with dance tunes, the sonata da chiesa was the same, but the dances were omitted. These forms gradually developed into the trio sonata of the Baroque – two treble instruments and an instrument, often with a keyboard or other chording instrument filling in the harmony. Both the bass instrument and the instrument would play the basso continuo part. During the Baroque period, chamber music as a genre was not clearly defined, often, works could be played on any variety of instruments, in orchestral or chamber ensembles. The Art of Fugue by Johann Sebastian Bach, for example, sometimes composers mixed movements for chamber ensembles with orchestral movements. Telemanns Tafelmusik, for example, has five sets of movements for various combinations of instruments, Baroque chamber music was often contrapuntal, that is, each instrument played the same melodic materials at different times, creating a complex, interwoven fabric of sound. Because each instrument was playing essentially the same melodies, all the instruments were equal, in the trio sonata, there is often no ascendent or solo instrument, but all three instruments share equal importance. In the second half of the 18th century, tastes began to change, many preferred a new, lighter Galant style. And clearly defined melody and bass to the complexities of counterpoint, now a new custom arose that gave birth to a new form of chamber music, the serenade. Patrons invited street musicians to play evening concerts below the balconies of their homes, their friends, patrons and musicians commissioned composers to write suitable suites of dances and tunes, for groups of two to five or six players. These works were called serenades, nocturnes, divertimenti, or cassations, the young Joseph Haydn was commissioned to write several of these

Duet
–
A duet is a musical composition for two performers in which the performers have equal importance to the piece. It is often used to describe a composition involving two singers and it differs from a harmony, as the performers take turns performing a solo section rather than performing simultaneously. In classical music, the term is most often used for a composition for two singers or pianists, a piece performed by two pianists performing together on the same piano is referred to as piano duet or piano four hands. A piece for two pianists performing together on separate pianos is referred to as a piano duo, duet is also used as a verb for the act of performing a musical duet, or colloquially as a noun to refer to the performers of a duet. The word is occasionally used in reference to non-musical activities performed together by two people. A musical ensemble with more than two solo instruments or voices is called trio, quartet, quintet, sextet, septet, octet, when Mozart was young, he and his sister Marianne played a duet of his composition at a London concert in 1765. The four-hand, described as a duet, was in many of his compositions included five sonatas. The first published sonata or duet was in 1777, in Renaissance music, a duet specifically intended as a teaching tool, to be performed by teacher and student, was called a bicinium. Duets have always been a part of the structure of operas, early 16th-century operas such as LOrfeo and Lincoronazione di Poppea involve duets throughout the performance. In 17th-century Italy duets were often used in comic scenes within serious operas, in Baroque France the duet was popular in tragedies, such as songs of vengeance and confrontation. The love duet was characterized by singing in close harmonies of 3rds and 6ths, some songs were written to be heard as conversations, such as Baby, Its Cold Outside. Others were performed around a theme, for example New York in Empire State of Mind, occasionally duets are an improvisation between artists, such as Under Pressure. David Bowie and Freddie Mercury reportedly composed the lyrics in a day by improvising together, the dictionary definition of duet at Wiktionary

Trio (music)
–
In music, a trio is a method of instrumentation or vocalization by three different sounds or voices to make a melodious music or song. In general, trio denotes a group of three instruments or voices. The term is used to describe a composition for such a group. The most common types of compositions are the piano trio—piano, violin and cello—and the string trio—violin, viola. In vocal music, the term terzet is sometimes preferred to trio, from the 17th century onward the word trio is used to describe a contrasting second or middle dance appearing between two statements of a principal dance, such as a minuet or bourée. This second dance was called a trio from the 17th-century practice of scoring it for three instruments, for example two oboes and bassoon. Later examples continued to be referred to as trios, even when they involved a number of parts. In the 18th century, the trio was also used to describe any instrumental composition for three unaccompanied musical strands, regardless of the number of instruments actually involved. Trios for a keyboard instrument are found in the music of Johann Sebastian Bach, for example his organ trios, BWV 525–30. Trio also occurs in the name for the musical form trio sonata, a trio sonata is written for two solo melodic instruments and basso continuo, making three parts in all, hence the name trio sonata. However, because the basso continuo is usually made up of at least two instruments, performances of trio sonatas typically involve at least four musicians, in rock music, bands most typically have four to five members, but there are also many three-person bands. Notable examples of trios following this pattern include Rush, The Police, Motörhead, however, there are other variations, for example Emerson, Lake & Palmer, where the guitar is replaced by a keyboard. Jimi Hendrix, although often remembered as a soloist, often performed as part of a trio, the Bee Gees were a popular trio during the Disco music era. A trio may also rely on a combination of instrumentation and vocal harmonization, crosby, Stills, & Nash began as a trio noted for their vocal congruence. Some trios rely entirely on the skills of the performers working in front of pre-recorded instrumental tracks. These include groups like Destinys Child and TLC, the New Grove Dictionary of Opera,4 vols.
